Sure. To paraphrase Kostya, as far as Android is concerned, intent
filters know nothing about home screen app widgets.
If you have one BroadcastReceiver in your manifest with an intent
filter, and you send a broadcast matching that filter, one
BroadcastReceiver will respond.
If you have two BroadcastReceivers in your manifest with the same
intent filter, and you send a broadcast matching that filter, two
BroadcastReceivers will respond.
If you have 1,337 BroadcastReceivers in your manifest with the same
intent filter, and you send a broadcast matching that filter, 1,337
BroadcastReceivers will respond.
This begs the question of why you have multiple AppWidgetProviders.
You only need one.
To tell small from large, call getAppWidgetInfo() on the
AppWidgetManager inside your onUpdate() or wherever. That will return
a Java object mirroring your <appwidget-provider> XML element. Use the
minWidth and minHeight values, or possibly the initialLayout value, to
determine which size it is.
